To avoid sending email for closed / canceled notifications, you must disable Mailer parameter "Send e-mails for canceled notifications" :
1- In OAM : Site Map / Notification Mailer / Edit / Advanced / Go to Step 4 (Message
Generation)
2- Untick the "Send e-mails for canceled notifications" checkbox
3- Apply changes
4- Bounce Mailer
This will stop all the cancelled notification e-mail for your instance across modules.
